To all 'whom t may concern.'

Be it known that I, THOMAS P. BoLGER,

y citizen of the United States, residing at Gloucester, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

The present invention relates to certain new and useful improvements in refrigerators, and more particularly to that type ofy refrigerators which are designed to be constructed from sheet metal the object of the invention being to provide a novel form of division bar for use between adjacent doors, whereby perfect insulation is obtained and the collection of moisture upon the exterior of the' refrigerator at any point is avoided.

A further object of the invention is to provide a refrigerator provided with a division bar between the adjacent doors which is simple and inexpensive in its construction, which can be readily maintained in a clean and sanitary condition, and which providesan effective insulation between the exterior of the division bar and the interior .of the refrigerator, thereby preventing the collection of moisture upon the outer face of the said division bar. f

`With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will morefully appear -as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which-t- Figure 1 is a front elevation of a sheetl metal refrigerator constructed in 'accordance with the invention. Fig. 2 is a horizontal sectional view -on the line 2-2 of Fig. 1, and Fig. 3 is a transverse vertical sectional View through the division bar hetween the doors, on the line 3-3 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral l designates the casing or body of the refrigerator which is provided .at the top thereof with an ice chamber 2 adapted to be closed by 'a door 3, and at the bottom thereof with a provision chamber' 4: adapted to be closed by a door 5. The walls of the main casing 1 are formed of outer and inner sheet metal plates 6 having an air space 7 between the same. lThe sheet metal walls G are each lined with a layer of waterproof ypaper 8, a layer of linofelt 9, and then a second layer of waterproof paper 10. rThe air space and the linings of waterproof paper and linofelt provide a perfect insulation and effectively-prevent the transmission of heat through the walls, and the said walls are designed to be made air tight, thereby preventing any moisture or odors from finding their way into the interior of the walls.

The division bar between the doors 3 and 5 has a novel construction whereby an air space is provided and the transmission of, heat thereby prevented, the said construction having the advantage of preventing objectionable accumulations of moisture upon the exterior of the division bar. vThis dvision bar comprises an outer flat strip 11 and an inner at strip 12, which are formed from sheet metal and have a parallel and spaced relation, thereby providing an air space 13 between the two strips. The inner strip 12 is wider than the outer strip 11 and extends upwardly and downwardly beyond the said outer strip so as to engage the edges of the doors 3 and 5 when thesaid doors are closed. These doors 3 and 5 are each provided at the exteriorV thereof with a marginal flange 14 which fits over and engages the outer strip 11 of the division bar. The doors are of such a thickness asto extend across and closethe top and bottom of the air space 13 when closed, andthe" inner edges of the doors are provided with packing strips 15 of rubber or other suitable material for engagement with the upper and lower edges of the inner strip-12 of the" division bar to insure a tight joint. The air space 13 between the outer and inner strips 11 and 12 of the division bar provides ,a perfect insulation whi'ch prevents the transmission of heat and thereby obviates any objectionable accumulations of moisture upon the. exterior of the' division bar. The air space 13 is open at the top and bottom thereof when the doors 3 and '5 are opei, and can be easily cleaned. The thickness of the doors 3 and 5, however, is suficient so thatthe edges of the doors lit over the top and bottoni of the air space 1 3 and close the same when the doors are shut.

Having thus described the invention, .what I claim as newand desire to secure by Letters Patent, is

l. A refrigerator including a casing formed with a pair of adjacent door openings, a division bar separating the door openings and formed of a pair of spaced and independent strips which provide an 'air space between the same, and doors for the door openings, the thickness of the doors serving to close the before mentioned air space between the spaced strips when the doors are shut. v

2. A refrigerator including a casing formed with a pair of adjacentdoor lopenings, a division bar between the door openings, the said division bar being formed of spaced and independent outer and inner strips having an air space between the same which communicates with the door openings, the inner strip being wider than the outer strip and projecting upon opposite sides thereof, and doors for the door openings, the said doors being adapted to engage the projecting edges of the inner strip when shut and the edges of the doors then serving' to close the air space between the outer and inner strips.

3. A refrigerator including a casing formed with a pair of adjacent door openings, a division bar betweenthe door openings, the said division bar being formed of independent spaced outer and inner strips having an air space between the same which communicates with the door openings and the inner strip being widerthan the outer strip so as to project upon opposite sides thereof, doors for the door openings, the thickness of the doors serving to close the before mentioned air space between the outer and inner strips when the doors are shut, and packing upon the inner faces of the doors for engaging the projecting edges of the inner strip when the doors are shut. In testimony whereof I aiix my signature in presence of two Witnesses.
